I have the Pinlock shield on my Shoei RF1100, and after thousands of fog-free miles, I now have a problem with fogging. When the shield is closed all the way, the top edge of the Pinlock insert sits and seals against the rubber gasket on the helmet. When I raise the shield from closed position, the gasket doesn't immediately "let go" of the Pinlock insert, so as I push the shield up, the Pinlock insert gets pushed down ever so slightly, enough to break its seal against the face shield. And with the Pinlock insert no longer sealed against the face shield, when I close the shield again it immediately starts to fog as the moisture from my breath gets under the Pinlock. And it STAYS fogged because there's not enough air circulating under the Pinlock, so raising the shield for a second won't clear it.

I now have to push the Pinlock insert back into place every time I raise my face shield, but it doesn't seal properly after the first time it happens, and it's pissing me off! Has anyone else had this issue? If so, how did you fix it?
